I had the droid2 before D2G and the keyboard is improved from the original slightly. They do function better for me and IMO the keys are slightly raised more than the original which makes it easier to type.

I exchanged my droid 2 for a droid 2 global within the 30 days verizon gives you. The global has a way better keyboard, little things like being able to use the top keys (especially in a case) keys being more like buttons and not a mat. Also the D2 Global is way faster than the Droid2 in every way. I used both phones for approximately 3 weeks.
